Abstract
Following a discussion on -boson mass observed at the CDF and ATLAS, we explore the parameter space allowed in the 2HDM+ model. Further, the model parameter space is constrained through vector-like leptons via muon measurements. We show our results for additional scalar mass fixed to and ~GeV keeping the standard Higgs-boson mass at 125~GeV in all four types of 2HDM+ model. The chosen mass of the singlet scalar is motivated by the excesses seen at the CMS and ATLAS data in proton-proton collisions at the Large Hadron Collider.
